ROAD-SCRAPER.

' Application filed May 31,

vTo all whom it may concern:

Be it known that I, FRANK BoniNn, a citizen of the United States,residing at Richwood, in the county of Becker and State of Minnesota,have invented new and useful Improvements in Ro.ad-Scrapers, of whichthe following is a specification. n

The invention relates to a road grader or leveler designed with a viewto providing a' wheeled implement which may be readily transported tothe place of use in comparatively compact form, and which in use may beadjusted to secure the desired result.

The improved road grader comprises a main beam in the form of a wheeledtruck, to which the leveling beams are connected in a manner to permittheir adjustment for various purposes.

The invention in the preferred form of details will be described in thefollowing specification, reference being had particularly to theaccompanying drawings, in which:

Figure 1 is a plan view of the improved road grader; Fig. 2 is a sideelevation of the same; Fig. 3 is a front elevation with the draftattachment omitted; Fig. 4 is a plan showing the leveling means in theinoperative position.

Referring particularly to the accompanying drawings, the improved roadleveler or grader comprises a main beam 1, of appropriate length,mounted at the respective ends 'upon ground wheels 2 and 3.

Combined with the main beam 1, are what I term leveling beams l andThese beams are of duplicate construction and each include a beam likeelement on the relatively inner-side and at the forward end is arrangeda scraper or cutting blade 6. The blade is secured to the edge of thebeam and is of concavo-convex formation in vertical section in order toprovide for a rolling or spreading of the material collected by thescraper. I The leveling beams are mounted at their rear ends to the mainbeam'by flexible connectors, such as chains 7 and the connee tionbetween the chains, which are fixed to the main beam and the levelingbeams, is

such that the length of the chains between the main beam and levelingbeams may be transferred at will, for a purpose which Will later appeal:

Each leveling beam isiprov'ided with a bar 8 secured to the uppersurface thereof, and projecting inwardly therefrom, the staySpecification of Letters Patent.

Thelevelingbeamsare each also provided with an upright post 10, whichthrough the medium of a chain 11 is connected to the chain 9, the mainbeam terminals of the chains 9 and 11, being arranged for adjustableconnection so that the lerigth of the chains may be transferred at wiThe main beam is. provided with a cross strut 12, of a length to permitthe disposi- .tion of the forward ends of the leveling beams thereon,uprights 13 being secured at the ends of the strut to prevent lateraldisplacement of the leveling beams when tachment of the draft animals,and at the rear end is provided a seat 14 for the operator.

Of course,in transport from place to place the leveling means are supported uponthe main beam and upon the strut 12.

Having described my invention, what I desire to secureby Letters Patentis A road scraper includlng a main beam, leveling beams arranged onopposite sides thereof, adjustable chain connections .hs-

tween the rear ends of the leveling beams and the main beam, chainssecured to the leveling beams and adjustably secured to the main beam tovary the distance ofthe forward ends of the leveling beams from the vmain beam at Wlll, rods rising vertically I from the leveling beams, andchains connected to the upper ends of said rods with the 'firstmentioned chains to tilting the leveling beams.

In testimony whereof I afiix my signature.
